In a study led by Barcelos and Sundstrom, the scientists used non-toxic chemicals, commercially available enzymes, and a specially engineered strain of yeast to convert wood into ethanol in a . cost of producing this type of ethanol. The longer you delay, the more likely it will develop bacteria. Despite its potential, cellulosic ethanol is expensive to make today. One class of sugars, the type with five carbon atoms, is broken off and harvested. Ingredients: Ethanol (45-50%) - 2 liters; Oak pegs/chips - 100 . Indeed, ethanol from such sources could replace "a very large fraction" of the gasoline currently used for vehicles, says Gregory Stephanopoulos, professor of chemical engineering at MIT. The cheap municipal waste Bolsen is talking about includes a lot of stuff usually headed for landfills. A wide variety of other. growing number worldwide are turning to wood, grasses and other Tens of billions of tons of plant cell-wall materials, including grasses, crop residues, wood chips, and some wastes, are produced worldwide each year. The optimized process shows enough promise to invest in scaling up the technology, says Colin South, Mascomas president. You have permission to edit this article. This slow transformation of wood chips into ethanol has been a bottleneck for companies that want to make money from the. While Mascoma has not achieved its ultimate goal of using a single genetically engineered organism to convert wood chips and other cellulosic raw materials into ethanol, the company has developed genetically modified bacteria that can speed up part of the process of producing ethanol. Hoping to capitalize on this potential, a handful of companies--including Celunol, in Dedham, MA; Iogen, in Ottawa, Canada, which has an existing demonstration scale plant and plans to scale up to commercial production; and the National Renewable Energy Laboratory (NREL), in Golden, CO--are working to develop better technology for making cellulosic ethanol. Using steam to rotate turbines generates electricity. and use the wood for the ethanol process. Of course, the steady supply of cellulosic waste products such as wood chips or the byproducts of sugar cane production is more efficient. I am not sure though if the energy extracted as fuel is going to come remotely close to being equal to the amount of energy required to be put into the system to get your products extracted. 1. Wouldn't that be methanol, or wood alcohol? Wyman estimates that the companys technology could produce ethanol for about the same cost as producing ethanol from corn, and eventually for less money. more time. And there's promising The teams found that woody biomass can be efficiently broken down and converted into advanced biofuels in a process that is cost-competitive with starch-based corn ethanol. This is if you are making the chips by hand. Indeed, ethanol from such sources could replace a very large fraction of the gasoline currently used for vehicles, says Gregory Stephanopoulos, professor of chemical engineering at MIT. Coskata says its ability to use a wide variety of feedstock to produce ethanol sets it apart from competitors locked into feedstock such as corn or sugar cane. and wood residue as base material, according to President Randy The company says its secret weapon is the process it uses to create the ethanol. Wyman estimates that the company's technology could produce ethanol for about the same cost as producing ethanol from corn, and eventually for less money. The company had received a $40 million Department of Energy grant to help finance the California plant but says a "challenging business climate" has pushed them to Mississippi instead.
